Patent JP-H04329806-A (JP)
Title: Apparatus for producing metallic powder
Inventor: YOSHINO MASANORI
IPC: B22F9/10
Filed: 1991-05-02
Abstract: PURPOSE:To continuously produce the metallic powder having stable quality by adjusting the flowing down speed of a cooling liquid by means of a layer thickness-adjusting ring. CONSTITUTION:The cooling liquid is ejected from an ejection pipe 7 along the inner peripheral surface of a cylindrical body 1. A cooling liquid layer 21 of a nearly specified inside diameter is formed by the layer thickness- adjusting ring and flows down while swirling until the liquid flows over the ring 6 and flows out downward. A molten metal 22 in an injection crucible 2 in the upper part of the cylindrical body 1 is then injected from a nozzle hole 15 toward the cooling liquid layer 21 and is parted by the swirling flow. This molten metal is rapidly solidified to powder. Since the swirling cooling liquid layer is formed by always the fresh cooling liquid, the layer is maintained at a specified temp. and since the layer is stable without disturbance of the liquid level, the rapidly solidified powder having the good quality is produced.

Title: Moving image encoder
Inventor: YAMADA YOICHI
IPC: H04N19/107
Filed: 1991-05-07
Abstract: PURPOSE:To prevent the deterioration of the performance of a device due to the change of a code amount caused by the inappropriate setting of a quantize step width by considering the characteristic of the picture of a processing block to be quantized in order to hold the code amount to be constant, at the time of deciding the quantize step width. CONSTITUTION:A code amount control means 20 supplies the code amount BR(m) of coded data which are coded from the start time of coding to the input time of the data of a processing block to be encoded. When the BR(m) is larger than a preliminarily set standard code amount BS, or when the BR(m) is assumed to be larger based on code amount presuming information S21, a quantize step width S22 applied to a quantizing means 7 is made to be increased. And also, when the BR(m) is smaller than the BS, or when the BR(m) is assumed to be smaller based on the S21, the S22 is made to be decreased. Thus, the appropriate setting of the S22 can be attained by considering the characteristic of the picture of the processing block to be quantized.

Title: Superelastic spring
Inventor: OONO AKIRA
IPC: F16F1/02
Filed: 1982-06-14
Abstract: PURPOSE:To make a permanent set remain behind as well as to expand a service temperature zone showing the degree of superelasticity, by giving a superelastic material a strain to the extent of its work hardening zone by slip deformation, while forming it into plastic deformation. CONSTITUTION:A superelastic alloy material of Ti-Ni, etc., is given such a strain as being beyond a superelastic zone and thereby turned into plastic deformation, making a permanent set remain behind by more than 10%. When the superelastic alloy is given a large strain beyond the superelastic zone, it enters a work hardening zone by slip deformation, producing the work hardening there, whereby the permanent set is left behind after load removal due to the plastic deformation by slippage. With this, the superelastic alloy shows its excellent superelasticity at a wide range of temperature zones so that any influence attributable to the service temperature is insignificant and a spring characteristic approximate to linearity can be secured.
